Effect Of A Yeast Culture Product (Yea-Sacc) On Feedlot Performance Of Yearling Cattle Self-Fed An All-Concentrate Finishing Diet, C. P. Birkelo, B. Rops
Effect Of A Yeast Culture Product (Yea-Sacc) On Feedlot Performance Of Yearling Cattle Self-Fed An All-Concentrate Finishing Diet, C. P. Birkelo, B. Rops
South Dakota Beef Report, 1995
Seventy-two yearling steers (initial weight 793 Ib) were allotted to 8 pens and self-fed a finishing diet consisting of 91 % whole shelled corn and 9% pelleted supplement without or with Yea-Sacc (11 g per day). Feed was provided to each pen approximately every 3days in amounts necessary to provide constant access during the 109-day trial. No treatment differences were detected for any of the feedlot performance or carcass characteristics measured. The occurrence of acidosis was high in both treatments as evidenced by the higher percentage of abscessed livers (40%). The feeding of Yea-Sacc did not have any beneficial effect …
Dosages Of Laidlomycin Propionate For Receiving And Growing Diets Fed To Steer Calves, R. H. Pritchard
Dosages Of Laidlomycin Propionate For Receiving And Growing Diets Fed To Steer Calves, R. H. Pritchard
South Dakota Beef Report, 1995
The inophore laidlomycin propionate2 (LP) became available in 1995 to improve ADG of cattle fed in confinement. Initial efficacy studies focused on finishing diets and yearling cattle. Limited data are available to quantify the benefits of using LP in calf grower programs. To evaluate LP efficacy for calves, receiving-grower diets based on corn silage were formulated to contain 0, 5.5, or 11 g/T LP and were fed to recently weaned steer calves. Five pens of 10 steers (initial BW = 483 Ib) were assigned to each diet. The grower phase was terminated after 98 days on feed. Final diet ionophore …
Evaluation Of Crude Protein Sources And Levels For High Growth Potential Yearling Steers Fed High Energy Diets, R. H. Pritchard
Evaluation Of Crude Protein Sources And Levels For High Growth Potential Yearling Steers Fed High Energy Diets, R. H. Pritchard
South Dakota Beef Report, 1995
Feedlot cattle are now capable of growth rates that greatly exceed our descriptions for established nutrient requirements. We must now redefined the impact of sources and levels of dietary CP on growth rate and efficiency. Pursuing this question, yearling steers (n = 360 x BW = 790 ± 10) were fed various levels and sources of supplement crude protein during a 120 day finishing period. Diets were formulated to contain 12 or 13% CP. Supplemental CP was provided in the forms of urea, soybean meal, bloodmeal, and feather meal. Actual dietary CP levels of 1 1.8% and 12.6% were lower …
Wheat Tailings In Feedlot Finishing Diets, C. P. Birkelo, B. Rops
Wheat Tailings In Feedlot Finishing Diets, C. P. Birkelo, B. Rops
South Dakota Beef Report, 1995
One hundred twenty-eight yearling steers (average initial weight 854 Ib) were fed one of four finishing diets containing (dry matter basis) either 1) 83% high moisture corn, 2) 44% high moisture corn and 37% high moisture wheat tailings, 3) 82% high moisture wheat tailings, or 4) 42% high moisture corn and 40% dry wheat tailings. Wheat tailings consisted of small wheat kernels removed during cleaning that had low test weights (41.5 to 52.0 Iblbushel) and high vomitoxin levels (1 7 to 42 ppm). High moisture wheat tailings were coursely cracked, reconstituted to 29% moisture, and ensiled. Dry wheat tailings were …
